continuous level monitoring Applications

The Environics Series Continuous Emissions Monitoring Calibration Systems (CEMCS) have been used in CEM vans and laboratories for over twenty years. They meet or exceed the performance requirements of the United States EPA 40 CFR Part 51 Method 205 Appendix M.
Our systems are custom built, computerized, mass flow controller based gas calibration systems which allow you to dilute a single high concentration cylinder of span gas to low levels for the calibration of gas analyzers.

The nature of steel manufacturing processes places severe limitations on the monitoring methods that can be used. Aggressive environments combined with high levels of particulates and gases make the choice very limited.

Discontinuous control is used mainly in smaller steam boilers with low output since the temperature fluctuations in the boiler are fairly great as a result of irregular refilling with water. Continuous control, on the other hand, permits still more economical steam generation with high quality.

The environment is one of today’s foremost concerns, and its preservation is among the biggest challenges we need to meet in coming years.
Saphymo offers a series of global solutions designed to detect the impact of a nuclear accident on the environment and local populations, and hence facilitate crisis management.
Our environmental monitoring networks and mobile devices continuously monitor artificial and natural radiation levels in air, water and soil, and provide data transmission to a central supervision station.
These solutions are internationally acclaimed for their autonomy, reliability, and ability to resist harsh environmental conditions.

In recent years the number of Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) plants for De-NOx have increased significantly. Continuous analysis of NOx prior to the de-NOx plant is often required to measure the concentration generated by the combustion process. This may be required to provide feed-forward to the Ammonia/Urea injection system and also to allow the effectiveness of the reduction process to be assessed. Continuous analysis of NOx post-reduction is required to allow the effectiveness of the reduction process to be assessed. It may also be beneficial to monitor NH3 slippage at this stage by calculating from the pre and post NOx levels if excess Ammonia/Urea is being applied.

Every day, wherever we go, we are exposed to minute amounts of environmental radiation.* This environmental radiation is emitted continuously, day and night, from various objects and substances in the natural world and our living environment.

meet governmental regulations, it is important to accurately monitor methane gas production, removal, venting, and burning. Knowledge of both methane flow and temperature at the flare stack can define when CH4 is being emitted to the atmosphere. The DX99 FlexPower™ Nodes can be installed in EX area with a Zone 0 ATEX certification. Use the analogue input to determine methane production levels and flow and use the thermocouple model to measure the temperature of a vent to verify the continuous combustion of methane.

The Data Explorer PC software for the XL2 Sound Level Meter now includes a series of professional tools for detailed analysis of low-frequency noise (LFN). The graphical representation of time varying frequency components offers an efficient process for identifying the presence and level of LFN. Also the associated high quality audio recording supports further correlation with the objective measurement data.
The new features are particularly useful in the calculation of immission levels which is defined as the cumulative noise energy to which an individual is exposed over time. Exposure to low-frequency noise over extended periods can lead to a range of health problems including cardio vascular disease, insomnia and depression. The sources of low frequency noise can often be attributed to electricity sub stations, chiller plants and incinerators with continuous noise at frequencies below 200 Hz.
XL2 Sound Level Meter records all Data
Measuring LFN requires a class 1 sound level meter

Ambient air pollution is a continuous problematic since many years, and the various organizations in charge of air quality monitoring work constantly on how to improve their structures and gain the most accurate and reliable data possible. Indeed, the changes in mentality and therefore in urbanism development for example, implies an access to the data faster and at multi-location level.
Air quality monitoring reference stations used nowadays measure with an extreme accuracy in located areas, but requires a lot of energy, financial investment (to purchase and to maintain) and space. It is not easy then to move them easily, or to multiply them to cover more accurately the area.
Cairsens sensors, installed under Cairtub or Cairnet formula perfectly address this problematic: autonomous, very compact, cost effective and ready to install systems, feature a viable alternative or or a complementary measurement methods to the existing reference networks.

Ormantine`s air monitoring equipment is widely used to monitor both indoor and outdoor air quality. Continuous development allows us to provide equipment for a broad range of applications, covering short-term and long-term monitoring. Pollutants can be detected even at very low levels – limits of detection are typically in the low parts per billion (ppb) range. Ormantine USA`s many solutions have applications from personal exposure monitoring to long term fence line monitoring studies.

Protea was asked to supply a high level ammonia (NH3) measurement system for a waste water treatment plant. The reflux drums at the inlet to two ammonia stripping towers needed to be measured continuously. Protea designed a solution based around ourSolus TDLAS analyserplatform and a high level dilution system. The Solus analyser was configured for NH3measurements in the range 0-500ppm. A dilution system incorporating special dilution probe and 19` control panel was installed before the analyser. This gave a dilution level of 600:1, enabling the NH3analyser to measure in the range 0-30% Volume.

AppliTek manufactures wet-chemical analyzers specifically designed for measuring on a continuous base the quality indices of drinking water, from raw water intake up to distribution level. Our systems have a small footprint, reduced reagent consumption and show excellent levels of detection in compliance with modern standards.

On top of that, the delivery of safe water throughout the water cycle will raise the need for efficient monitoring systems detecting in real-time contaminations. `Broadband toxicity`, a non-specific parameter defined by AppliTek, is a prodigiously new and clean technology for safeguarding drinking water.

Fugitive emissions can be a health concern during removal and disposal of mercury-contaminated material at remediation sites. Thus, remediation projects either indoors or outdoors often require on-site, real-time mercury air monitoring with a Tekran2537. This assures permitted levels are not exceeded during waste processing and human exposure levels are below government regulated toxicity thresholds. Often multiple sites must be monitored continuously.The Tekran1115 Multi-Port Sampleris the ideal tool for multiplexing the Tekran2537 for real-time continuous on-site monitoring of mercury fugitive emissions.

The oil and gas industry requires major infrastructure in terms of refineries and offshore extraction platforms which operate continuously. A large number of essential rotating machines, structures and piping networks are subjected to high levels of demand in a difficult environment, leading to the potential for breakage.

A large pharmaceutical plant runs a Thermal Oxidiser on plant to incinerate their solvent-containing gas streams before emission. When the oxidiser is offline, then the plant must monitor the release of solvent to the atmosphere. A ProtIR 204C fixed monitoring system was installed that continually measures 24 plant solvents, including Acetone, Cyclohexane, DCM, DMF, IPA, MIBK, Toluene and THF. Given the high levels that are possible, the system has an active dilution system, reducing the concentration of the measured gas in the analyser to levels that can be analysed simply. Chemometric modelling enables interferences from the overlapping absorption spectra to be accounted for, ensuring accurate analysis of all 24 gases.

Gradko’s ambient air monitoring equipment is widely used to monitor both indoor and outdoor air quality. Continuous development allows us to provide equipment for a broad range of applications, covering short-term and long-term monitoring.
